Enum CryptoError 

pub enum CryptoError {
    InvalidKey,
    InvalidPem(String),
    EncryptionFailed,
    DecryptionFailed,
    BadPadding,
    Base64(String),
    Io(Error),
}

Errors produced by the crypto module.

Variants enumerate the small fixed set of failure modes the engine reports up to its callers. The opaque OpenSSL error stack is preserved when relevant so operators can correlate failures with the underlying library log.

Variants

InvalidKey

A symmetric or asymmetric key was malformed or had the wrong length.

InvalidPem(String)

A PEM file did not contain a recognisable RSA private key.

EncryptionFailed

Symmetric or asymmetric encryption failed.

DecryptionFailed

Symmetric or asymmetric decryption failed.

BadPadding

PKCS#7 padding on a decrypted block was malformed.

Base64(String)

A base64 input was malformed.

Io(Error)

Underlying I/O failure (file open, read, write).

Trait Implementations

impl Debug for CryptoError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for CryptoError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for CryptoError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<Error> for CryptoError

fn from(source: Error) -> Self

Converts to this type from the input type.
